If you need another setting, you can modify the settings i.e. in
apache-activemq-5.11.0/bin/env or create one of the files mentioned in
the help output of the script:

*Configuration of this script:**
**The configuration of this script is read from the following files:**
**    **/etc/default/activemq /home/mschoechlin/.activemqrc
/home/mschoechlin/myroot/apache-activemq-5.11.0/bin/env**
**    This script searches for the files in the listed order and reads
the first available file.**
**    Modify /home/mschoechlin/myroot/apache-activemq-5.11.0/bin/env or
create a copy of that file on a suitable location.**
**
**    To use additional configurations for running multiple instances on
the same operating system**
**    rename or symlink script to a name matching to
activemq-instance-<INSTANCENAME>.**
**    This changes the configuration location to
/etc/default/activemq-instance-<INSTANCENAME> and**
**    $HOME/.activemqrc-instance-<INSTANCENAME>.*
